Droop Control
Droop Control is a function that allows the speed of a motor to decrease in proportion
to load torque. This can be used to insure load sharing between drives on multiple
drive systems.
Range:0.0 to 100.0%
Factory Default:
0.0%
A setting of 100% allows the speed to drop 100% of the maximum speed value
(when the torque is 100%).
Droop response time is set with parameter B7-02.
Setting Range:
0.00 to 1.00s
Factory Default:
0.10s
When B7-02 is decreased, drooping response becomes quicker, but the motor
hunts more easily.
